 Description
 ===========

-MPOS is a web based Mining Portal for various crypto currencies. It was created by [TheSerapher](https://github.com/TheSerapher) and has hence grown quite large. Recently it was migrated into a Github Organization to make development easier. It's a community driven open source project. Support can be requested on IRC at https://webchat.freenode.net/?channels=#mpos

-
-**NOTE**: This project is still under development and commits are happening on a daily basis.
-I do not recommend using this for a live setup as of yet. Wait for the later Release Candidate
-if you wish to run your pool with it. Testing pools are much appreciated though!

-When you decide to use `MPOS` please be so kind and leave the footer intact. You are not the author of the software and should honor those that have worked on it. I don't mind changing the LTC donation address at the bottom, but keep in mind who really wrote this software and would deserve those ;-).

+Please take a look at the [Quick Start Guide](https://github.com/TheSerapher/php-mpos/wiki/Quick-Start-Guide). This will give you an idea how to setup `MPOS`. Please be aware that the `master` branch is our currently considered stable system while `development` is used as a test bed for all upcoming changes for `master`. If you wish to run a stable, well tested system ensure you run `git checkout master`. If you decide to stick to the `development` branch with bleeding edge code and potential bugs, just `git clone` the project.
